4+1 View model designed by Phillippe Kruchten. It is used for describing the architecture of software-intensive systems, based on the use of multiple , concurrent views. The views are used to describe the system from the viewpoint of different stakeholder , such as end users , developers , system engineer , and project managers. The four views of the model are logical , development , process and physical view.

2. Process Views - It deal with the dynamic aspect of the system .

3. Development Views - It will illustrates a system from a programmer 's perspective.

4. Physical Views - It depicts the system from the system' engineer points.
